Hi, I have tested import 3d object from my 3d artist. I can’t get smooth shadow and the curves are not smooth too. Any idea/advice?
Here is my simple test.

Control key are arrow key and w, a, s, d
Realtime shadows are basically created using shadowmapping, which means that the quality of the shadows are controlled partly by the shadow parameters (read the docs!) and light placement.
Regarding “curves” not being smooth - you may want antialiasing (or a more finely modelled scene, depending on what you mean). Again, read the docs.
Is there a reason you’re not baking lighting/shadows into this scene? Sure looks to me like a good candidate for shadow baking, and save realtime shadows for animated/moving objects. It would give you a lot more control over the shadows also.
Thanks for advice. It just for me to test real time shadow feature.
Take a look at this page on how to tweak shadow quality for your scene:

Thanks for the links. 
Hi, I have set to fantastic setting but I still get jagged image. Please check the image. . Look at the arrow. Is it a problem when I import the fbx file?
That’s because you don’t have anti-aliasing on.

Yes, I know but somehow it not working. Please look at my setting.
did you quit reopen unity? (i think that still needs to happen for AA to update in editor)
The screen capture is which I running from the output.
i think all full screen camera effects (like glow) disable it too, though your shot desn’t seem to have any.
Also your Mac may not support FSAA. Intel GMA 950s found in Mac minis and MacBooks, for example.

So, can I try it on Windows machine?
I try to change anti-aliasing setting. There is no different result between disabled, 2x and 4x. Is it a problem with my graphic card?
I get same result on my pc with nVidia 8800 GTS.
K, solved. I have to choose spotlight.
